Hi Erik, This is fine. But I need to know how to convert from WGS84 lat-long into a meter grid so I can do the trig.

The function in MapX to do this takes two WGS-84 lat/long points. I don't have two lat/long points. I have one lat/long, an angle in degrees and a length in meters. I need to calculate the second lat/long (unless there is a MapX function that can draw a line - given a position, angle and distance). A C++ algorithm to do it would be fine. I can't believe MapX doesn't support such a calculation.

IOW do you not know how to go about it?

I want to calculate a new point based on a bearing and distance from this position. Difficult bit - I want to calculate this using MapX, or alternatively I could use some C/C++ code. Thanks for any help with this Kind regards Tim Smith --------------------------------------------------------------------- List hosting provided by Directions Magazine | www.directionsmag.com | To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] Message number: 12390 ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
